VISUALIZATION PEAK AND AVERAGE VALUES
Pressing at the same time the
A
and
B
keys, on
F
display will appear the
average and maximum stored value, that are selected using the
B
key while
a luminous segment on the
G
display indicates the type of the maximum
and/or average value.
AVG
: the average values are calculated on a average time set. The
calculation is at fixed window and it’s sinchronized when the instrument turn
on.
The stored maximum values are the two types:
MAX
: the instantaneous maximum values store the maximum value
achieved by the parameter of measure for at least one second.
MAX AVG
: the average maximum values (maximum demand) store the
maximum value achieved in the average time as set in the setup menu;
The integration for the calculating of the average values is synchronized all the time that the instrument turn on.
Press
A
and
B
keys another time to come back to the measures visualization. The instrument will come back to the
measure visualization automatically if for 10 seconds no one button is pressed.
The average value, the maximum value and the maximum average value selectable with
B
key are the following:

NOTE relative to the measure
The refresh time of the display is lower of a second and it depends by the time of calculating of the measure and concerning the
methodology of measure used in the way to allow a comfortable reading of value also in presence of fast variation of the measure
parameter.
If the multimeters are used on single phase lines, the measures are referred at the phase L3. The other data displayed and relative
to the three-phase system must not considered.
If the measure indicated by the instrument are not reliable or absurd it’s necessary to verify the connection of the measure inputs of
currents and voltages because must be respected the sequence of the phase, the corresponding of the currents and voltages of the
same phase (the L1 voltage phase and the TA located on L1 phase must be connected on the L1 input) and the sense of the
current (the S1 terminals of the TA must be connected at the S1 terminals of the instrument).
In some application where the secondary is connected to other instruments apart from the ELM multimeter, some problems could
happen concerning the typology of the amperometric inputs.
If there are some problem call the assistance service.
